Optimization of nano coating to reduce the thermal deformation of ball screws

Abstract To reduce the thermal deformation of ball screws, process nano coating preparation for on screws to temperature rise and thereby was discussed in this article. Simultaneously, cooling mechanism presented. The channels relatively even distribution graphene were observed scanning electron microscopic images. In terms coating, optimization design carried out obtain optimized material ratio nozzle flow through orthogonal experiment. influence parameters reducing also discussed. experimental results show that maximum rise, deformation, time reach balance decreased by 12.5, 69.1, 46.3%, respectively. effectiveness validated experimentally.
